Shopping in your closet

I am definitely smaller, my tighter beige pants are fitting better. I'm also going to go through my dresses/skirts to see what fits now. The last two days I wore a dress and a skirt that looked great and weren't borderline tight.  Are any of you now wearing sizes in your closet that you weren't able to get into for a long time?  What are you doing with your "too big" clothes?  I am currently a 4-6.  I am contemplating getting rid of the size 10 pants.  I think that if I reach my goal (4) and have 6 as post-holiday/vacation clothing, I would be fine.  I am still going to hold onto some small 8s, but the 8-10, why keep them?  One reason I started Dukan was I didn't want to start buying clothes in a larger size.  If I get rid of the 8-10, then I will be more mindful of staying within my weight limits, as I won't have clothes to wear.  Thoughts?
